The group said that in the year to 31 December 2017, its UK and Ireland arm posted a 26% increase in operating profit to £265.9mn.

Aldi also highlighted that its ‘Specially Selected’ range is comprised of some of its best-performing products and now generates annual sales of more than £1bn (US$1.3bn).

Today, Aldi has more than 775 stores in the UK and Ireland, with a 7.6% share of the grocery market, according to data from Kantar Worldpanel.

Giles Hurley, the chief executive of Aldi UK and Ireland, said: “The revolution in British grocery shows no sign of slowing.”

“In 2020, Aldi will have been serving British shoppers for 30 years. In that time, we’ve become part of the fabric of British life. We’re proud to be reaffirming our commitment today.”

He added that whilst other grocers “introduced more complexity into their businesses in their struggle to win back customers”, Aldi would stick to “what it does best – buying smart, staying lean, improving quality and keeping prices low.”
